Michael C. Malin and Kenneth S. Edgett of Malin Space Science Systems published research in the journal Science based on images from NASA's Mars Global Surveyor spacecraft. The two researchers had found that the images showed massive sedimentary deposits on Mars, suggesting that the planet "was once a water-rich land of lakes." Malin described the images as revealing "hundreds and hundreds of identically thick layers," features that were "almost impossible to have without water." J. William Schopf, head of the Center for the Study of Evolution and the Origin of Life at the University of California at Los Angeles, commented that the images provided the "strongest evidence yet for what appear to be sedimentary units on Mars," supporting the theory that, billions of years ago, Mars had been wetter, warmer, and possibly hospitable to life. 1063
Hatches between the ISS and Space Shuttle Endeavour opened for the first time, and the three members of the space station crew, who had been living aboard the ISS for five weeks, received their first visitors. ISS Commander William M. Shepherd commended Endeavour's crew for their installation of the giant solar array on the space station. The two crews spent their day together transferring supplies, such as food, water, mail, and gifts, to the space station and removing trash, damaged items, and unneeded items for return to Earth.
